Architecture and dedication[edit]
Columbia Square was built for KNX and as the Columbia Broadcasting System's West Coast operations headquarters on the site of the Nestor Film Company, Hollywood's first movie studio. The Christie Film Company eventually took over operation of Nestor Studios and filmed comedies on the site, originally the location of an early Hollywood roadhouse. Prior to moving to Columbia Square, KNX had been situated at several Hollywood locations.
Columbia Square was designed by Swiss-born architect William Lescaze[1] in the style of International Modernism and built over a year at a cost of two million dollars — more money than had ever been spent on a broadcasting facility.
Lescaze's sweeping streamline motifs, porthole windows and glass brick were true to Modernist design, though CBS President William Paley insisted the Square's form follow function. In his dedicatory speech, he remarked, "It is because we believe these new Hollywood headquarters, reflecting many innovations of design and acoustics and control, will improve the art of broadcasting that we have built them and are dedicating them here tonight."
Columbia Square opened April 30, 1938, with a full day of special broadcasts culminating in the star-studded evening special, "A Salute to Columbia Square" featuring Bob Hope, Al Jolson and Cecil B. DeMille. Crowds thronged Sunset Boulevard and a blimp bathed in searchlights hovered overhead as the program was carried coast-to-coast on the Columbia Broadcasting System, beamed to Europe via short wave, and carried across Canada on the CBC. On that premiere broadcast, Hope joked that Columbia Square looked like "the Taj Mahal with a permanent wave." Jolson quipped, "It looks like Flash Gordon's bathroom."
The Square's original configuration included eight studios. Studios 1 through 4 were to the left of the main entrance. Upstairs were Studios 5 through 7 and at the rear of the forecourt was the large auditorium referred to as the "Columbia Playhouse" that seated 1050. In 1940, two new audience theatres were added to the east of the auditorium called "Studio B" and "Studio C" each seating approximately 350 people. Shows such as Jack Benny's Lucky Strike Program and The Adventures of Ozzie and Harriet originated from Studio B. Lucille Ball's My Favorite Husband, Blondie, and Dr. Christian are a few of the shows that broadcast from Studio C. When B and C were built, the Columbia Playhouse then took the letter designation of "Studio A". Studio A was home to The Silver Theatre, The Swan Show starring George Burns and Gracie Allen, The Lady Esther Screen Guild Players and countless others. The complex included Brittingham's Radio Center Restaurant, a men's clothing store, and a branch of the Bank of America. Tours of the studios cost 40 cents and passed by a glass-windowed control room housing Columbia's West Coast master control.
"Columbia Square was one of the glories of radio. It was somewhat sacred to those in the industry. There was nothing comparable to its splendor in New York" says writer-producer Norman Corwin whose most famous broadcast, On a Note of Triumph, originated from the Square on VE Day, 1945.
In early 2009, the Los Angeles Cultural Heritage Commission and the City Council designated CBS Columbia Square Studios as a historic-cultural monument.

Programs[edit]
Columbia Square became home to some of the best-known comedies of radio's golden age. Jack Benny, Burns and Allen, Edgar Bergen, Red Skelton, Eve Arden (Our Miss Brooks), Jack Oakie and Steve Allen sparked to the airways from the Square.
Dramas included Suspense; Gunsmoke; and Man Behind the Gun, written, directed and produced by William N. Robson; Dr. Christian, "The Whistler", Yours Truly, Johnny Dollar, The CBS Radio Workshop, where author Aldous Huxley introduced a production of Brave New World and Columbia Presents Corwin — dramas produced by Norman Corwin.
Musical acts that performed at Columbia Square included Eddie Cantor, Rosemary Clooney, Bing Crosby and Gene Autry. Composer Bernard Hermann frequently scored and conducted Columbia Square broadcasts. Through the facilities of KNX, the Columbia network broadcast big band music from nearby ballrooms including the Hollywood Palladium and the Earl Caroll Theater.
In the late 1940s and early 1950s Columbia Square also served as a CBS television facility. In 1948, the first West Coast-based variety program, The Ed Wynn Show, was produced on Stage A. Lucille Ball's first national TV appearance took place on The Ed Wynn Show in December 1949 (aired on the East Coast just after New Year). Within the year Stage A would be the location of the shooting of the pilot episode of I Love Lucy.
In the 2005 KNX broadcast, A Salute to Columbia Square, announcer George Walsh recalled crowds jamming the Square's forecourt for tickets to live broadcasts. (Ushers would sometimes walk down Sunset Boulevard to NBC's studios at Vine Street to urge audience members to watch a Columbia Square broadcast instead.) After their on-air appearances, actors would dash to the Radio Actors Telephone Exchange in the Square's lobby to check with their agents about their next bookings.
Bob Crane was a top-rated KNX deejay at Columbia Square in the 1960s and James Dean worked as an usher. Some of the Square's once-luxurious radio theaters were converted to recording studios for Columbia Records where Bob Dylan, Barbra Streisand and many other top stars recorded albums.

Adaptive reuse[edit]
KNX moved into new studios in the Miracle Mile neighborhood on L.A.'s Wilshire Boulevard which it shares with CBS Radio stations KFWB, KTWV, and KRTH. KNX, the last radio station to operate in Hollywood, moved after 67 years of operation at the Square just after 11:00 p.m. August 12, 2005, following a farewell broadcast from its Columbia Square studios. On April 21, 2007, KCBS-TV and KCAL-TV left the building and moved their operations to the CBS Studio Center in Studio City, thus ending Columbia Square's status as a broadcast facility, one of a very few remaining in Hollywood.[2]
The Square fell into disrepair during the years in which Laurence Tisch chaired CBS, and asbestos problems were cited as a reason to demolish the venue. Sungow Corp acquired Columbia Square in 2003 for $15 million. Las Vegas-based developer Molasky Pacific LLC, acquired the property in August 2006 for $66 million. It planned to redevelop the 125,000-square-foot (11,600 m2) complex to continue to attract entertainment industry tenants and is considering options that would add some residential units to the office and broadcasting facility. The project is valued at $850-million and is the largest development project in Hollywood, California. The redevelopment of the historic CBS Studios on Sunset was approved in 2009 with a controversial 28-story tower. Developer Kilroy Realty Group acquired the project in 2012 and changed plans — when completed the new Columbia Square will feature a 20-story residential tower with 200 apartments, 33,000 sq ft (3,100 m2) of retail, three renovated historic structures, two new office buildings with an additional 330,000 sq ft (31,000 m2) of space, and four and a half levels of underground parking.[3][4][5][6] The development is currently under construction as of 2014.
In fall 2007, producer Viacom, owner of CBS until 2006, chose the site for MTV's The Real World: Hollywood.
The National Trust for Historic Preservation and Los Angeles Conservancy have been actively engaged in efforts to preserve the Hollywood landmark.[7][8]
